Age of a vine?

[M38A1]

I'm assuming grape varietals grow at different rates from one type to another. Could you throw a wild guess on how old this Muscadine trunk root might be? It's about 10" in diameter and in front of the cedar tree trunk. It produces about 20 branches from there which run up and over a cedar tree that's approximately 20' high, then spreads out about 50-75' in all directions. Just curious if one can 'age' something like this. It's wild for sure. I have another one that grows along a fence line which acts like a prefect trellis. Now how lucky is that?
